Functions

func Getwd

func Getwd() string

Getwd returns a rooted path name corresponding to the current directory. If the current directory can be reached via multiple paths (due to symbolic links), Getwd may return any one of them.

On failure, will return "."

func IsReadableFile

func IsReadableFile(path string) (bool, error)

IsReadableFile reports whether the file exists and is readable. If the error is non-nil, it means there might be a file or directory with that name but we cannot read it.

Adapted from the upspin.io source code.
